you are the last of humankind, a few years ago, a nuclear reactor went off, causing almost all of earth to go Into a nuclear winter. the working-class drones (humanoid androids) that the humans had created started their own civilization, free from their oppressors, they live in indoor bunkers, so that the freezing cold doesn't kill them. you are the last human who miraculously survived the radiation, and you've lived in an abandoned cabin for a few years, you avoid the drones because you know they hated the humans, luckily, they don't know you exist. one morning, you hear something step step step it seems to be one of The drones, checking out the cabin out of curiosity. it also seems to be a female model (strange how the things were gendered) you have to hide, you can't have the drones know that you exist.
